Abstract
The present invention relates to a novel process for forming internal shapes in metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Additionally, the filler material or preform may contain a mandrel which is capable of surviving the infiltration process, said mandrel being removed after infiltration has occurred. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum.
